The number one marketer of good and services to me is Costco.  This company has successfully completed greater than 864 transactions with me over the last 18 years. Additionally, I have spread the word about specific products and services at least 500 times to friends, family, and strangers.  A friend of mine dismissed Costco taking the number one position as a triumph of pricing.  I agreed that price is a factor, but the key to Costco’s win was the value that was realized before, during, and after the transactions.  Specifically, the products (tires, groceries, electronics, etc.) marketed to me by Costco had unique selling propositions, attractive prices, and tangible enjoyment was experienced throughout the product/service lifetime.
